Do use something unusual like pollirq or something?
We only have in saa7134-core.c
/* initialize hardware #1 */
saa7134_board_init1(dev);
saa7134_hwinit1(dev);
/* get irq */
err = request_irq(pci_dev->irq, saa7134_irq,
IRQF_SHARED | IRQF_DISABLED, dev->name, dev);
if (err < 0) {
printk(KERN_ERR "%s: can't get IRQ %d\n",
dev->name,pci_dev->irq);
goto fail3;
}
and in saa7134-alsa.c
err = request_irq(dev->pci->irq, saa7134_alsa_irq,
IRQF_SHARED | IRQF_DISABLED, dev->name,
(void*) &dev->dmasound);
if (err < 0) {
printk(KERN_ERR "%s: can't get IRQ %d for ALSA\n",
dev->name, dev->pci->irq);
goto __nodev;
}
Have fun ;)
